  • One tenancy agreement accepted per property, except for HMOs where multiple tenancy agreements are accepted

Accepted. Applies when applicant simultaneously completes a mortgage for the same or greater amount keeping the same interest rate for that portion of the new mortgage without incurring an early repayment charge. Subject to meeting the company's lending criteria at the time of application.

Private sales

Will be considered subject to evidence of deposit and confirmation of:

  • How the applicant sourced the property
  • Any relationship between the applicant and the vendor
  • Whether the property is being purchased at full market value. (Please let us know if there are any incentives)
    • Properties being purchased for more than 10% below the market value will not be considered (unless purchased from a recognised developer and the discount/incentive can be evidenced).

Please note, we won't accept private sale applications where the applicant is related to the vendor or the vendor is a Limited Company (except for New Builds).

Sale and rent back

It is not permitted for the vendor to remain as a tenant in the property or to retain an interest in the property.

Property Investment Clubs / Companies

Applications to purchase properties sourced via Property Investment Clubs/Companies are not accepted. These are typically businesses which offer to buy a property quickly from a seller, and then sells it on to another buyer.


All Buy to Let properties must be used for residential purposes only and be in a lettable condition, to be determined by the valuer.
